Coding and computer science for kids
Looking for coding for kids that actually builds something? Kids aged 8–15 learn to create a real website step by step – with a project and a certificate.
How does this work?
Show me
Every lesson first shows you finished code and explains exactly what it does. One click and you can copy it.
Your turn
Then you get a task for your own project. Stuck? Every task has a hidden solution you can peek at.

Pick your project
Every lesson works for all four projects. Pick the one that excites you most.
Remember your choice – it will follow you through every lesson.
My school's website
A schedule, lunch menu, photos from school events and teacher profiles. A website your school could actually use.
My personal website
A page about you: what you love, what you can do, your creations and hobbies. Your own spot on the internet.
Travel journal
A map of your trips, holiday photos and stories from your travels. A site you keep adding new adventures to.
Sports club website
Team roster, match results, training schedule. A site for your team, club or group of friends.
Pick a level by age
Levels 1–2 are free. From Master onward it's a one-time payment – access lasts forever. No need to rush – every level builds on the previous one.
Level 1 from age 8 free
Builder
HTML & CSS. Build your whole website from the first page to publishing it on the internet. Nothing tricky to install – just an editor and a browser.
Level 2 from age 11 free
Wizard
JavaScript. Your website starts reacting: dark mode, photo galleries, quizzes. Pages that can actually do things.
Level 3 from age 13 7 €
Master
React & Node.js. Rebuild your site the way the pros do it, and give it its own server with a guestbook.
Level 4 from age 14 10 €
Data pro
Git, GitHub & SQLite. Your code is backed up, and your data survives a server restart.
Level 5 from age 15 14 €

AI & APIs. Your website fetches the weather, shows a map, and gets its own chatbot that knows your project.
Level 6 from age 15 18 €
Project lead
Domain, HTTPS, automatic deployment and launch day. Your project becomes a real product at its own address.
